SCRUBIBING-MACI-IINE.

Specification of Letters Patent.

Patented Nov. 19, 1912.

Application filed May 4, 1912. Serial No. 695,129.

To all whom it may concern:

Be it known that I, JOHN SwIoN'rnK, a subject of the Emperor ofAustria-Hungary, residing at Pittsburgh in the county of AL legheny andState of Pennsylvania, have invented certain new and useful Improvementsin Scrubbing-Machines, of which the following is a specification,reference beinghad therein to the accompanying drawing.

This invention relates to a scrubbing machine, and the primary objectofmy inven; tion is to provide a novel machine that can be easily andquickly moved over a floor or other surface for scrubbing, cleaning andremoving foreign matter that adheres to the floor.

Another object of this invention is to provide a scrubbing machineembodying reciprocatory brushes that can be adjusted to compensate forwear. The machine also embodies a mopping roll and provision is made forwringing the roll. I

A further object of this invention is t provide a floor scrubbingmachine that is durable, comparatively inexpensive to manufacture, andhighly efficient for the purposes for which it is intended.

With the above and other objects in view, the invention resides in anovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed. I

Reference will now be had to the drawings, wherein there is illustrateda preferred embodiment of my invention, but it is to be understood thatthe structural elements are susceptible to such variations as fallwithin the scope of the appended claim.

In the drawing like numerals denote corresponding parts throughout theseveral views in which Figure 1 is a plan view of the scrubbing machine.Fig. 2 is a side elevation of the same. Fig. 8 is a perspective view ofa portion of the frame of the machine, showing one of the brush guides.Fig. 4 is a longitudinal sectional view of the scrubbing machine. Fig. 5is a cross sectional View of the same, showing the mopping roll. Fig.dis a perspective view of a drip pan. Fig. 7 is a perspective view of aportion of a brush holder. Fig. 8 is a perspective view of a detachedbrush clamp, and Fig. 9 is a perspective view of a portion of a brush.

The reference numeral 1 denotes 2. rectangular frame having parallellongltudinal side walls 2. The side walls 2, at the ends thereof areprovided with bearings 3 for revoluble wheels 4 that support the frame 1above the surface of a floor 5.

The inner sides of the walls 2, adjacent to the ends thereof, areprovided with longitudinal channel shaped guides (5 and these guides areoppositely disposed and adjustably held in engagement with the walls 2by bolts 7 and winged thumb nuts 8.

The side walls of the frame are provided with a series of vertical slots9. As illustrated each of the walls is provided with four slots. Eachguide (3 extends across a pair of slots 9 and is provided with a pair ofbolts 7 which project through the slots associated with their respectiveguide. The nuts 8 are mounted upon the outer ends of the bolts 7 andengage the outer face of the side walls so that the guides are heldfirmly in the desired position.

Slidably mounted in the channel shaped guides 6 are the ends of brushholders 10 and each holder, contiguous to the ends thereof is providedwith a set of straps 11. Arranged in the straps 11 are the inner ends ofclamping members 12, the inner ends of said members being bent upwardlyto provide apertured lugs 13 that are connected together by a screw 14and a knurled nut 15, as best shown in Figs. 1 and 1. The outer ends ofthe clamping members 12 terminate in depending heads 16 that engage inlongitudinal grooves 17 provided therefor in the body 18 of a scrubbingbrush 19. The scrubbing brushes are arranged transversely of the frame 1and the bristles of sa1d brushes are adapted to engage the floor 5, asbest shown in Fig. 2. As the bristles of the brushes are worn, theguides 6 are adjusted relatively to the frame 1 whereby said brushes canbe used until completely worn out.

The side walls 2 intermediate ends thereof, are provided with inwardlyprojecting) brackets 20 for bearing 21. Revolubly mount-ed in saidbearings is a shaft 22 that has crank portions 23. These crank portionsare oppositely disposed and are loosely connected to pit-men 24: thathave the outer ends thereof pivotally connected to lugs 25 carried bythe brush holders 10.

One of the side walls 2, intermediate the ends thereof, is provided withan auxiliary frame 26 that extends at right angles to the main frame 1.Revolubly mounted in the auxiliary frame 26 are shafts 27 and 28 thathave sprocket wheels 29 over which passes an endless sprocket chain 30.The shaft 27 has one end thereof extending through the side walls of theauxiliary frame 26 and is provided with a hand wheel 31 having a crankor handle 32. The shaft 28 has a beveled gear wheel 33 meshing with asimilar wheel 34 that is mounted upon the end of the crank shaft 22.

The side walls 2, at the rear end of the machine, are provided withvertical oppositely disposed slots 35 and guide members 36 at the upperedges of said side walls. slidably mounted in the guide members 36 arethe ends 37 of a yoke 38. The lower ends of the yoke 38 are providedwith bearings 39 for a transverse bolt or shaft 40 i that extendsthrough the slots 35 of the side walls 2.

Revolubly mounted upon the bolt or shaft 40 is a mopping roll,comprising a hub 41 and heads 42 and 43, the former being formedintegral with the hub 41 and the latter detachable. Detachably mountedupon the hub 41 is a cylindrical mop 44 made of felt or an absorbentmaterial.

Encircling the ends of the yoke 38, between the guides 36 and thebearings 39, are coiled compression springs 45, said springs retainingthe mopping roll normally upon the floor 5, whereby it will absorb waterand moisture upon the floor.

J ournaled in the side walls 2, adjacent to the mopping roll is a shaft46 having one end thereof provided with a crank 47 and a handle 48.Mounted upon the shaft 46 be tween the side walls 2 is a wringing roller49.

WVhile .the scrubbing machine is moved back and forth over the floor 5with one hand, the other hand can be employed for operating the handwheel 31, whereby a rotary movement will be imparted to the crank shaft22 and the brushes l9 reciprocated through the medium of pit-men 24. Asthe brushes are reciprocated the surface of the floor 5 is thoroughlyscrubbed. After the mopping roll has absorbed a quantity of water, theyoke 38 is elevated to place the periphery of the roll in engagementwith the roller 49. This roller is revolved to wring the mopping roll,and it is preferable to place a drip pan beneath the mopping roll whilewater and other matter is wrung from the same. It is apparent thatconsiderable pressure can be brought to bear upon the roller 49 by themopping roll. Consequently the felt or other material from whichthe'roll is made will be compressed to liberate the water held insuspension thereby.

The manner of connecting the brushes 19 to the holder 10 permit of saidbrushes being removed from time to time and thoroughly cleaned.

hat I claim is V A scrubbing machine comprising a portable frame,brushes c'arried thereby, vertically disposed guide members carried bythe rear of said frame, a yoke slidably mounted in said guide membersand having the arms thereof provided with bearings, a shaft extendingthrough said arms and mounted in said bearings, a mopping roll mountedupon said shaft and provided with a hub, a, mop.

detachably mounted upon said hub, and resilient means connected to theyoke for maintaining the mopping roll normally upon the floor.

In testimony whereof I aflix my signature in the presence of twowitnesses.
